Count the number of multicheck options selected

Notes

In our work at SpotDev, we keep encountering scenarios where our clients need to know the number of options selected in a multicheck property. 

For example, a company might contain information about the specific products a customer has purchased - the client needs that information and their reporting needs to know the total number of products they have. 

You can solve this problem a few ways. But, if you want to do so with a custom-coded workflow action, this function will count the number of items ticked/checked on a multicheck property and output the value as an int. 

You can then use a standard workflow action to copy the value of your output to a number property. 

Code

        
Language:  


        
 
exports.main = async (event, callback) => {
  const valueList = event.inputFields['valueList'];
  let valueCount; 
  const allValues = valueList.split(';');
  valueCount = allValues.length;
  
  console.log(allValues);
  console.log(`Number of values selected is ${valueCount}`);
 
  callback({
    outputFields: {
      valueCount: valueCount
    }
  });
}
